This product is a polymer-modified cementitious waterproofing material formulated from a unique formula. The introduction of United States technology, the use of permeable crystalline material to the penetration mechanism of concrete, is the base surface to form an integral consistent integrated composite waterproof material with double waterproof function. When applied to the desired area, it can penetrate into the base material to form branch-like crystals, blocking the channels of water molecules in the structure, thus achieving a waterproof effect.
